## Summary description

Schneider Electric A9Z01440 is a 4-pole residual-current device (RCD) Type A designed for AC and pulsating DC residual currents. Rated for 380–415 V input voltage with a rated current of 40 A and rated voltage 380 V, it features a 30 mA sensitivity and 500 A breaking capacity. Suitable for residential, commercial and light industrial protection against earth leakage currents.

## Long description

Schneider Electric A9Z01440 is a 4-pole residual-current device (RCD) Type A designed to detect and interrupt AC and pulsating DC residual currents in low-voltage installations. Rated for a nominal current of 40 A and a sensitivity of 30 mA, this device is intended for use on 380–415 V three-phase systems. With a breaking capacity of 500 A and a compact 4P format, it provides earth-leakage protection that meets common safety requirements for residential, commercial and light industrial electrical circuits.
Advantages
The Type A characteristic enables detection of both alternating residual currents and pulsating direct residual currents, extending protection beyond standard AC-only devices. The 4-pole design ensures all phases and neutral are monitored simultaneously, reducing the risk of unnoticed leakage paths. Its 30 mA sensitivity is tuned for personal protection against electric shock while the 40 A rated current suits typical branch circuits. The device’s construction and rated breaking capacity provide reliable disconnection under fault conditions.
Suitable for
 Three-phase distribution boards in residential buildings
 Small commercial premises and retail units
 Light industrial installations requiring earth-leakage protection
 Circuits with electronic equipment that can produce pulsating DC residual currents
When it may not be suitable
This RCD is not intended for applications that require higher rated currents than 40 A or sensitivity other than 30 mA. It is not a substitute for devices designed specifically for high-energy industrial networks or for protection against overcurrent where a circuit breaker with specific tripping curves is required. For environments with continuous DC leakage or special grounding systems, a different protection strategy may be necessary.
Key specifications
 Poles: 4P (four-pole)
 Type: A (detects AC and pulsating DC residual currents)
 Rated current: 40 A
 Residual operating current (sensitivity): 0.03 A (30 mA)
 Nominal voltage range: 380–415 V (three-phase)
 Rated breaking capacity: 500 A
 Application: earth-leakage protection for low-voltage circuits
How to use
Install the Schneider Electric A9Z01440 in the distribution board on a compatible DIN rail according to local wiring regulations and the manufacturer’s mounting instructions. Connect all phase conductors and neutral through the device so that leakage current is detected across all poles. Ensure the line and load terminals are wired correctly and torqued to the specified values in the technical documentation. After installation, perform routine tests by pressing the test button to verify the trip mechanism operates and carry out periodic insulation and leakage checks as part of normal maintenance.
What to consider before purchase
 Ensure the nominal system voltage and the device voltage range (380–415 V) match the installation.
 Confirm that 40 A rated current is appropriate for the protected circuit and coordination with upstream and downstream protective devices.
 Verify that Type A detection (AC and pulsating DC) meets the residual current characteristics of connected equipment.
 Check available space in the distribution board for a 4-pole device and compatibility with DIN-rail mounting.
